BACK-BAND HOOK FOR HARNESS.

EPiCIFIGATION formingpart of Letters Patent No. 288,128, dated November6, 1883.

Application filed March I, 1883. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM C. SHERARD, a citizen of the United States,residing at Mon,- terey, in the county of Abbeville and State of SouthCarolina, have invented certain new and useful Improvements in Back-BandHooks for Harness, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in back-band hooks for harness;and it consists in the application of a key or spring-catch to the frameof the hook, whereby the strap is securely fastened in the buckle, toprevent it from slipping by any strain which may be brought upon it. aswill be hereinafter more fully described.

Figure 1 is a plan view of the buckle and hook. Fig. 2 is asectional-view on waof Fig. 1. Fig. 3 is an end view. Fig. 4 is atransverse section on y y, Fig. 1.

A represents the frame of an ordinary buckle, having a hook, A, on oneside and a bar, A, in the middle, with the teeth a a immediately in themiddle line, 2 z.

B B are loops or ears, having in each an eye, 72.

O is a key. (Shown in dotted lines in Fig. 1 and solid lines in Fig. 2.)It has at one end a head, 0, and at the other end a spring-catch, c,which is riveted to the top ofthe key; and there is a recess, 0, on topdeep enough for the spring c to fall into when pressed down for thewithdrawal of the key. Key C has also in its under surface a groove, d,as seen 3 5 in the section, Fig. 3. This groove cl is immediately overthe line of teeth a a on the bar A, and it will be seen in Fig. 4 thatwhen the key 0 is forced into the eyes 2') the back-strap E will befirmly held by the teeth a a, as no amount of strain put upon the strapcan sepa rate it from the teeth.

The use of the key with the teeth a a placed immediately on the middleline of the bar A, I claim as an improvement upon the backband hooksheretofore used, where the teeth are set beyond the middle line and atan angle thereto, as in such buckles the strap or trace is aptto bepulled off from the teeth.

I claim 1. Abaek-band or trace hook having a key to cover the strap andkeep it upon the teeth of the middle bar, substantially as and for thepurpose described.

2. A back-band or trace hook provided with 55 perforated ears, and amiddle bar having a row of vertical teeth on top, in combination with akey having a spring-catch on top and a groove underneath, substantiallyas and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM C. SHERARD.
